CROSS-REFERENCE TO PRIOR APPLICATION

This application is a continuation of International Patent Application No. PCT/CN2020/142461, filed on Dec. 31, 2020. The entire disclosure is hereby incorporated by reference herein.

FIELD

This application relates to the technical field of electronic vaporization apparatus, and in particular, to an electronic vaporization apparatus, a vaporizer thereof, and a vaporization core thereof.

BACKGROUND

Generally, the existing electronic vaporization apparatus can vaporize vaporization liquid such as e-liquid. The electronic vaporization apparatus typically includes a vaporization core, which includes a liquid absorbing assembly and a heating assembly. The liquid absorbing assembly is in communication with a liquid storage space of the vaporization liquid, so that the vaporization liquid in the liquid storage space can seep out from the liquid absorbing assembly. The heating assembly is disposed on the side of the liquid absorbing assembly away from the liquid storage space of the vaporization liquid, so as to heat and vaporize the seeped vaporization liquid.

However, when the existing vaporization core heats and vaporizes high-viscosity vaporization liquid, since the high-viscosity vaporization liquid has poor fluidity, it may not replenish itself to the liquid absorbing assembly in time, which causes dry heating occurring in the vaporization core, thereby producing a burnt flavor and a peculiar flavor.

SUMMARY

In an embodiment, the present invention provides a vaporization core, comprising: a liquid absorbing assembly comprising a bottom wall and a side wall connected to a side of the bottom wall, the bottom wall comprising a vaporization surface facing away from the side wall; and a heating assembly fixedly disposed on the liquid absorbing assembly comprising a heat generating element and an electrode portion connected to the heat generating element, the heat generating element comprising a heat generating portion and a first embedding portion, wherein the heat generating portion and the electrode portion are disposed in the bottom wall and exposed to the vaporization surface, and the first embedding portion is embedded in the bottom wall and corresponds to the side wall.

Referring to FIG. 1 , FIG. 1 is a schematic structural diagram of an embodiment of a heating assembly according to this application.

The heating assembly 100 includes a heat generating element 110 and an electrode portion 120 connected to the heat generating element 110. The heat generating element 110 includes a heat generating portion and a first embedding portion 1101. The electrode portion 120 includes an electrode body 121 and a second embedding portion 1201. The first embedding portion 1101 and the second embedding portion 1201 are both configured to be inserted into a preset liquid absorbing assembly (which may specifically refer to the liquid absorbing assembly 200 described below).

In this embodiment, the heating assembly 100 may include two electrode portions 120. The two electrode portions 120 are respectively connected to two opposite ends of the heat generating element 110.

The heat generating element 110 may be formed by being bent multiple times and includes a plurality of first linear units 111 and a plurality of first embedding portions 1101. Two adjacent first linear units 111 may be connected to each other by one first embedding portion 1101. The heat generating portion of the heating assembly 100 may be constituted by the plurality of first linear units 111.

In this embodiment, the plurality of first linear units 111 may be disposed in a first plane. Two opposite ends of the plurality of first linear units 111 are connected to the first embedding portions 1101. The first embedding portions 110 at the two opposite ends of the first linear units 111 may be disposed in a second plane and a third plane respectively. The second plane and the third plane are both intersected with the first plane.

Further, each first embedding portion 1101 may include at least one second linear unit 112 and a third linear unit 113.

That is, the side surface of each third linear unit 113 is completely covered by a porous ceramic material of the liquid absorbing assembly, and the end portions of each third linear unit 113 are connected to the adjacent second linear units 112.

Alternatively, in other embodiments, the heat generating element 110 may be formed by being bent multiple times and includes a plurality of first linear units 111 and a plurality of second linear units 112. That is, the heat generating element 110 includes no third linear unit 113. Each first embedding portion 1101 may include two second linear units 112. Two ends of the two second linear units 112 may be connected to each other at an angle, and the other two ends of the two second linear units 112 may be connected to two first linear units 111 respectively.

In this embodiment, the electrode portion 120 includes the electrode body 121. The electrode body 121 is connected to the heat generating element 110, and is configured to be connected to a connecting wire. The second embedding portion 1201 may be connected to the electrode body 121. In an embodiment, the second embedding portion 1201 is integrally formed with the electrode body 121. The second embedding portion 1201 enables the electrode body 121 to be stably fixed on the liquid absorbing assembly, thereby avoiding the problem such as invalid connection or poor contact between the electrode body 121 and the connecting wire caused by loosening of the electrode body 121.

The plurality of first linear units 111 and the electrode bodies 121 in the two electrode portions 120 may be all disposed above the first plane. For example, the plurality of first linear units 111 and the electrode bodies 121 in the two electrode portions 120 are all sheet-like, and all disposed above the first plane and parallel to the first plane. The plurality of third linear units 113 are disposed in a fourth plane that is parallel to and spaced apart from the first plane. That is, a connection line of the centers of the plurality of first linear units 111 in the heat generating element 110 may be disposed in the first plane, a connection line of the centers of the plurality of third linear units 113 in the heat generating element 110 may be disposed in the fourth plane, and the first plane is parallel to and spaced apart from the fourth plane. The plurality of second linear units 112 in the heat generating element 110 may connect the plurality of first linear units 111 to the plurality of third linear units 113. Specifically, two opposite ends of each second linear unit 112 may be connected to the first linear unit 111 and the third linear unit 113 respectively. The plurality of second linear units 112 that are located at one end of the first linear units 111 may be disposed in a second plane, and the plurality of second linear units 112 that are located at the other end of the first linear units 111 may be disposed in a third plane.

In this embodiment, the height of the first embedding portion 1101 may be equal to or approximately equal to the length of the second linear unit 112. The height of the first embedding portion 1101 may be ranged from 0.5 mm to 4 mm, such as 0.5 mm, 1 mm, 2 mm, 3 mm, and 4 mm.

Further, in this embodiment, in a case that the heat generating element 110 is formed by being bent multiple times and includes the plurality of first linear units 111, the plurality of second linear units 112, and the plurality of third linear units 113, a bending portion may be formed between two connected linear units (the first linear units 111, the second linear units 112, or the third linear units 113), and the bending angle of the bending portion is ranged from 10° to 170°. The connected first linear unit 111 and the second linear unit 112 are herein used as an example, the first linear unit 111 and the second linear unit 112 are both linear, the bending portion may be a joint between the first linear unit 111 and the second linear unit 112, and the bending angle of the bending portion may be ranged from 10° to 170°. Preferably, the bending angle of the bending portion may be ranged from 80° to 100°. For example, the bending angle of the bending portion between the first linear unit 111 and the second linear unit 112 may be set to 80°, 90° or 100°. In a preferred embodiment, the bending angle of the bending portion may be an obtuse angle.

The included angle between the first embedding portions 1101 and the first plane may be equal to or complementary to the included angle between the first embedding portions 1101 and the first linear units 111. The included angle between the first embedding portions 1101 and the first linear units 111 may be set to 90° to 170°, such as 90°, 100°, 110°, 130° or 170°. That is, the included angle between the first embedding portions 1101 and the first plane is 10° to 90°.

Further, the included angle between the second embedding portions 1201 and the electrode bodies 121 may be the equal to the bending angle of the bending portions between the second embedding portions 1201 and the electrode bodies 121. The included angle between the second embedding portions 1201 and the electrode bodies 121 may be an obtuse angle, and may be set to be 90° to 170°. That is, the included angle between the second embedding portions 1201 and the first plane may be 10° to 90°.

In this embodiment, the included angle between the first embedding portions 1101 and the first plane may be set to be equal to the included angle between the second embedding portions 1201 and the first plane. In addition, the first embedding portions 1101 and the second embedding portions 1201 located on the same side of the heat generating element 110 may be disposed in the same plane or in two parallel and spaced apart planes respectively.

In other embodiments, the included angle between the first embedding portions 1101 and the first plane may be set to be different from the included angle between the second embedding portions 1201 and the first plane. That is, the plane where the first embedding portions 1101 are located is intersected with the plane where the second embedding portions 1201 are located, thereby improving the stability of the heat generating element 110 embedded in the liquid absorbing assembly.

Optionally, the second embedding portion 1201 as a whole may have a rectangular, a square, a triangular or an I shape.

Further, in this embodiment, each electrode body 121 may be provided with a plurality of second embedding portions 1201. The plurality of second embedding portions 1201 may be respectively disposed at different side ends of the electrode body 121, and connected to the edges of the electrode body 121.

In this embodiment, each electrode body 121 is provided with two second embedding portions 1201, and the two second embedding portions 1201 are respectively disposed on two opposite sides of the electrode body 121. In other embodiments, the side edge of each electrode body 121 away from the heat generating element 110 may be connected with a second embedding portion 1201. Optionally, at least two second embedding portions 1201 are mounted to each side edge (which is not connected to the heat generating element 110) of each electrode body 121. A through hole 1202 may be defined in each second embedding portion 1201.

In this embodiment, the heat generating element 110 may be integrally formed with the electrode portions 120. For example, the heating assembly 100 may be made of a metal sheet, and the heating assembly 100 may be formed by pressing and bending the metal sheet.

Alternatively, the heat generating element 110 and the electrode portions 120 may be separate structures, which may be fixed together by welding, so as to form the heating assembly 100.

The heat generating element 110 may be a metal bar or a metal wire. The heat generating element 110 may have any one of a circular cross section, a square cross section, a rectangular cross section, an elliptical cross section. In other embodiments, the cross section of the heat generating element 110 may have a shape of a regular polygon, such as a regular hexagon, a regular octagon.

Further, in this embodiment, the heat generating element 110 may be a metal bar or a metal wire, or may be a patterned metal sheet. The heat generating element 110 may be made of any one of iron-chromium alloy, iron-chromium-aluminum alloy, iron-chromium-nickel alloy, chromium-nickel alloy, titanium alloy, stainless steel alloy, Karma alloy, or may be made of a mixture of at least two of them.

In a case that the heat generating element 110 is a metal bar or a metal wire, the diameter of the cross section of the heat generating element 110 may be in a range of 0.02 mm to 1.00 mm, such as 0.02 mm, 0.5 mm, or 1 mm. In a case that the heat generating element 110 is a metal sheet, the thickness of the heat generating element 110 may be in a range of 0.01 mm to 2 mm.

In a case that the heat generating element 110 is formed by being bent and includes the plurality of first linear units 111, the plurality of second linear units 112, and the plurality of third linear units 113, the length of each bending portion may be set in a range of 0.1 mm to 5 mm. For example, the length of each bending portion may be set to 0.1 mm, or 2.5 mm, or 5 mm.

As described in the foregoing embodiments, the heat generating element 110 with the three-dimensional structure is formed by being bent multiple times. In other embodiments, the heat generating element 110 with the three-dimensional structure may be formed by one or more approaches such as die stamping, casting, machine weaving, chemical etching.

Alternatively, in other embodiments, a plurality of heat generating elements 110 may be mechanically woven into a mesh structure, and then the mesh-shaped heating assembly is bent, to form the heat generating element 110 with the three-dimensional structure.

Alternatively, a plurality of small-diameter sub-heat generating elements may be used, to form a large-diameter heat generating element 110 by means of winding, bonding or welding. Then, the large-diameter heat generating element 110 is bent, to form the three-dimensional structure including the plurality of first linear units 111, the plurality of second linear units 112, and the plurality of third linear units 113.

Further referring to FIG. 1 , in this embodiment, a plurality of micro-pores 101 may be defined in the heat generating element 110. The micro-pores 101 may be through holes or blind holes defined in the heat generating element 110. The micro-pores 101 help to enhance the stability of the combination of the heat generating element 110 and the liquid absorbing assembly, and make the heat transfer more uniform. Further, by defining the micro-pores 101, the liquid absorbing assembly can be partially exposed, which allows the liquid to be heated to seep out through the surface of the liquid absorbing assembly exposed by the micro-pores 101, thereby evenly heating the liquid to be heated.

The plurality of micro-pores 101 may be provided, and the plurality of micro-pores 101 may be sequentially spaced apart along the longitudinal direction of the heat generating element 110. In this embodiment, the plurality of micro-pores 101 may be disposed in the first linear units 111, the second linear units 112, or the third linear units 113. In other embodiments, the plurality of micro-pores 101 may be disposed in the first linear units 111, the second linear units 112, and the third linear units 113.

In a case that the micro-pores 101 defined in the heat generating element 110 are through holes, the through holes may be circular holes, and the diameters of the through holes may be set to 0.01 mm to 1.00 mm. For example, the diameters of the through holes may be set to 0.01 mm, 0.5 mm or 1 mm.

In a case that the micro-pores 101 defined in the heat generating element 110 are blind holes, the blind holes may be circular holes or rectangular holes. In a case that the blind holes are circular holes, the diameters of the blind holes may be set to 0.01 mm to 1.00 mm. In a case that the blind holes are rectangular holes, the widths of the blind holes may be set to 0.01 mm to 1.00 mm, and the lengths of the blind holes may be set to 0.10 mm to 2.00 mm.

The spacing between two adjacent micro-pores 101 may be set to 0.03 mm to 1.00 mm.

Therefore, in this embodiment, by defining the plurality of through holes in the heat generating units of the heat generating element 110, the stability of the combination of the heat generating element 110 and the liquid absorbing assembly can be further improved. This can enable the heat generated by the heat generating element 110 to be uniformly diffused into the liquid absorbing assembly, so as to prevent the occurrence of heat accumulation in a local area of the heat generating element 110 due to poor contact with the liquid absorbing assembly, thereby causing the problem that the local temperature of the heat generating element 110 is too high. In addition, it can also ensure that the liquid absorbing assembly can quickly and evenly raise the temperature. Therefore, the vaporization effect on the vaporization liquid is improved.

Referring to FIG. 2 to FIG. 4 , FIG. 2 is a schematic structural diagram of an embodiment of a vaporization core according to this application, FIG. 3 is an exploded diagram of the vaporization core shown in FIG. 2 , and FIG. 4 is a schematic structural diagram of the vaporization core shown in FIG. 2 after a rotation of 180°.

The vaporization core 20 includes the liquid absorbing assembly 200 and the heating assembly 100. The vaporization core 20 may be configured to heat vaporization liquid, so as to vaporize the vaporization liquid.

The liquid absorbing assembly 200 may be defined with or include a plurality of micro-pores therein, so as to form a porous body. The vaporization liquid may enter the liquid absorbing assembly 200 through the micro-pores, or may seep from one side of the liquid absorbing assembly 200 to the other side through the micro-pores. The plurality of micro-pores in the liquid absorbing assembly 200 may store the vaporization liquid. The heating assembly 100 is partially buried in the liquid absorbing assembly 200. The liquid absorbing assembly 200 includes a vaporization surface 201 and a liquid absorbing surface 202. The liquid absorbing surface 202 may be in contact with the vaporization liquid, so that the vaporization liquid enters the liquid absorbing assembly 200 through the liquid absorbing surface 202. The vaporization liquid in the liquid absorbing assembly 200 may be further transferred from the liquid absorbing surface 202 to the vaporization surface 201, so as to be heated and vaporized on the vaporization surface 201.

The liquid absorbing assembly 200 may be made of a porous ceramic material. Specifically, the liquid absorbing assembly 200 may be made of any one or more of alumina, silicon oxide, silicon nitride, silicate and silicon carbide.

Specifically, a powder material (or slurry) of a mixture of any one or more materials such as alumina, silicon oxide, silicon nitride, silicate and silicon carbide may be used to form the blank of the liquid absorbing body 200, and the heating assembly 100 is at least partially buried in the pre-blank. By heating and sintering, the liquid absorbing assembly 200 in which the heating assembly 100 is partially buried is formed, and the heating assembly 100 is closely attached to the liquid absorbing assembly 200.

The shape and the size of the liquid absorbing assembly 200 are not limited, which may be selected according to requirements.

In this embodiment, specifically, the liquid absorbing assembly 200 includes a bottom wall 210 and a side wall connected to a side of the bottom wall 210. The heating assembly 100 may be embedded in the liquid absorbing assembly 200, and the first embedding portions 1101 of the heating assembly 100 may be disposed corresponding to the side wall, so that the vaporization liquid close to the side wall can be preheated by the first embedding portions 1101.

The side wall may be an annular side wall 220. The annular side wall 220 may be connected to the side of the bottom wall 210, and a liquid storage groove 211 is surrounded by the side wall 220 and the bottom wall 210. The first embedding portions 1101 may pass through the bottom wall 210 and be partially inserted in the annular side wall 220.

The vaporization surface 201 may be disposed on the outer surface of the bottom wall 210, and the first embedding portions 1101 and the second embedding portions 1201 of the heating assembly 100 may be inserted into the liquid absorbing assembly 200 from the vaporization surface. Specifically, the plurality of first linear units 111 and the electrode bodies 121 of the heating assembly 100 are embedded in the bottom wall 210. The first embedding portions 1101 may pass through the bottom wall 210 and be partially inserted in the annular side wall 220. The second embedding portions 1201 are all accommodated in the bottom wall 210.

In this embodiment, by partially embedding the first embedding portions 1101 of the heating assembly 100 into the annular side wall 220, the vaporization liquid at the liquid absorbing surface 202 can be preheated. When the viscosity of the vaporization liquid is high, the vaporization liquid can be preheated, thereby improving its fluidity. As such, the vaporization liquid can quickly enter the liquid absorbing assembly 200 through the liquid absorbing surface 202, and the rate of the vaporization liquid in the liquid absorbing assembly 200 flowing to the vaporization surface 201 can be enhanced, so as to timely replenish the vaporization liquid to the vaporization surface 201, thereby avoiding the problem of dry heating of the vaporization core 100.

The outer surface of the bottom wall 210 facing away from the annular side wall 220 is the vaporization surface 201 of the liquid absorbing assembly 200. The vaporization liquid can be heated and vaporized at a position of the vaporization surface 201. The surface of the annular side wall 220 of the liquid absorbing assembly 200 away from the bottom wall 210 may be in contact with the vaporization liquid to form the liquid absorbing surface 202, so that the vaporization liquid can enter the liquid absorbing assembly 200 through the liquid absorbing surface, and seep out through the vaporization surface 201 the bottom wall 210. When the vaporization liquid seeps out through the vaporization surface 201, the part of the heating assembly 100 located outside the liquid absorbing assembly 200 can heat and vaporize the seeped vaporization liquid.

An opening of the liquid storage groove 211 is defined in the side of the annular side wall 220 facing away from the bottom wall 210, and the opening of the liquid storage groove 211 allows the vaporization liquid to enter the liquid storage groove 211. Therefore, the inner wall of the liquid storage groove 211 can form the liquid absorbing surface of the liquid absorbing assembly 200. By defining the liquid storage groove 211, the area of the liquid absorbing surface 202 can be increased, so that the contact area between the vaporization liquid and the liquid absorbing assembly 200 can be increased, thereby facilitating the vaporization liquid to seep into the liquid absorbing assembly 200.

The outer contour of the annular side wall 220 may substantially have a rectangular shape. The first embedding portions 1101 of the heating assembly 100 at two opposite sides may be respectively inserted into the part of the side wall corresponding to the two opposite long edges of the annular side wall 220. The first embedding portions 1101 may be buried in the part of the side wall corresponding to the two opposite long edges of the annular side wall 220 respectively.

In this embodiment, by embedding the heating assembly 100 in the liquid absorbing assembly 200, the heating assembly 100 can be closely attached to the liquid absorbing assembly 200, thereby making the heat transfer of the heating assembly 100 more uniform. In addition, by embedding the heating assembly 100 in the liquid absorbing assembly 200, during the process of the vaporization liquid seeping from the liquid absorbing surface to the vaporization surface, the heating assembly 100 can preheat the vaporization liquid in the liquid absorbing assembly 200, so as to uniformly increase the temperature of the vaporization liquid, thereby improving the vaporization effect of the vaporization liquid. By inserting the first embedding portions 1101 of the heat generating element 110 into the annular side wall 220, the liquid to be vaporized in the liquid storage groove 211 can be preheated, thereby further improving the vaporization effect of the vaporization liquid.

In this embodiment, further, the heating assembly 100 is disposed to have the three-dimensional structure, thereby further improving the vaporization effect of the vaporization liquid.

Further, as shown in FIG. 6 , the heating assembly 100 is buried in the liquid absorbing assembly 200. Specifically, exposed surfaces of the plurality of first linear units 111 and the electrode bodies 121 may be flush with the outer surface of the bottom wall 210.

Alternatively, referring to FIG. 8 , in other embodiments, the heating assembly 100 may be disposed to partially protrude out of the outer surface of the bottom wall 210.

In this embodiment, a protruding portion 212 is disposed on the inner surface of the bottom wall 210, and the protruding portion 212 may be connected to the annular side wall 220. The protruding portion 212 may be disposed parallel to the short edges of the annular side wall 220, and two opposite sides of the protruding portion 212 may be respectively connected to the part of the side wall corresponding to the two opposite long edges of the annular side wall 220. By providing the protruding portion 212, the protruding portion 212 can be immersed in the liquid to be vaporized in the liquid storage groove 211. The protruding portion 212 can transfer the heat of the annular side wall 220 and/or the bottom wall 210 to the liquid to be vaporized in the liquid storage groove 211 more quickly and uniformly, so as to preheat the liquid to be vaporized in the liquid storage groove 211, thereby further improving the vaporization effect of the vaporization liquid.

Optionally, at least two protruding portions 212 are disposed, and two adjacent protruding portions 212 may be spaced apart to form a V-shaped groove or an arc-shaped groove. Further reference may be made to FIG. 1 and FIG. 2 .

In this embodiment, the two electrode bodies 121 of the heating assembly 100 may respectively form the positive and negative electrodes of the heat generating element 110. The two electrode bodies 121 are electrically connected to the positive and negative electrodes of an external power supply, so as to supply power to the heat generating element 210, thereby allowing the heat generating element 210 to generate heat.

A through groove 1202 may be defined in the second embedding portion 1201. When the second embedding portion 1201 is embedded in the blank of the liquid absorbing assembly 200, the powder or slurry forming the liquid absorbing assembly 200 may enter the through groove 1202. After the sintering and fixing of the blank of the liquid absorbing assembly 200 is completed, the stability of the combination of the heating assembly 100 and the liquid absorbing assembly 200 can be further enhanced.

Further, referring to FIG. 6 , in this embodiment, the thickness L1 of the bottom wall 210 is 0.5 mm to 4 mm. The height L2 of the annular side wall 220 is 0.5 mm to 4 mm, and the wall thickness of the annular side wall 220 is greater than 0.8 mm.

Further, this application further provides a vaporizer. Referring to FIG. 9 and FIG. 11 , FIG. 9 is a schematic structural diagram of an embodiment of a vaporizer according to this application, FIG. 10 is a cross-sectional diagram of the vaporizer shown in FIG. 9 , FIG. 11 is a partial enlarged diagram of a region A of the vaporizer shown in FIG. 9 .

The vaporizer 30 includes a vaporization sleeve 310, a mounting base 320, and a vaporization core 20.

The vaporization sleeve 310 includes a liquid storage cavity 312, a vent tube 314 is disposed in the vaporization sleeve 310, the liquid storage cavity 312 is configured to store the vaporization liquid, and the vent tube 314 is configured to guide vapor to a mouth of the user.

The mounting base 320 includes a first pressure regulating channel 322, a liquid inlet cavity 321, and a vapor outlet 323. The first pressure regulating channel 322 is circuitously disposed at the periphery of the liquid inlet cavity 321. The mounting base 320 is embedded in the vaporization sleeve 310. The first pressure regulating channel 322 and the liquid inlet cavity 321 are both in communication with the liquid storage cavity 312. The liquid inlet cavity 321 guides the vaporization liquid to the vaporization core 20, so that the vaporization core 20 vaporizes the vaporization liquid to form vapor. The vent tube 314 is connected to the vapor outlet 323, to guide the vapor to an oral cavity of the user through the vapor outlet 323.

The vaporization core 20 is connected to the end of the mounting base 320 away from the liquid storage cavity 312 and blocks the liquid inlet cavity 321, so that the vaporization sleeve 310, the mounting base 320, and the vaporization core 20 form a liquid storage space. After the vaporization liquid is stored in the liquid storage space, the vaporization liquid closes the first pressure regulating channel 322 by liquid seal.

When an outer atmospheric pressure changes or a balance between an atmospheric pressure in the liquid storage cavity 312 and the outer atmospheric pressure is lost due to inhalation, for example, when the atmospheric pressure in the liquid storage cavity 312 is excessively large, the vaporization liquid may leak between the mounting base 320 and an inner wall of the vaporization sleeve 310, or the vaporization liquid may leak from the vaporization core 20, or the vaporization liquid may leak from a joint between the vaporization core 20 and the mounting base 320. Alternatively, when the atmospheric pressure in the liquid storage cavity 312 is excessively low, due to the influence of atmospheric pressure difference between the inside and the outside of the liquid storage cavity 312, the vaporization liquid may not flow smoothly, and the vaporization core 20 may generate a burnt flavor during operation due to insufficient liquid supplying, leading to poor inhalation experience to the user.

Further, this application provides an electronic vaporization apparatus. Referring to FIG. 12 , FIG. 12 is a schematic structural diagram of an embodiment of an electronic vaporization apparatus according to this application.

The electronic vaporization apparatus 40 includes a vaporizer 30 and a body assembly 410. The vaporizer 30 may be configured to store and vaporize the vaporization liquid, so as to form vapor that is configured to be inhaled by a user. The vaporizer 30 may be mounted on the body assembly 410. A power supply assembly is disposed in the body assembly 410. After the vaporizer 30 is mounted on the body assembly 410, the positive and negative electrodes of the power supply assembly in the body assembly 410 may be electrically connected to two electrode bodies 121, so as to form a power supply circuit, thereby supplying power to the heat generating element 110.

To sum up, this application has the following beneficial effects. By embedding the heating assembly in the liquid absorbing assembly, the heating assembly can be closely attached to the liquid absorbing assembly, thereby making the heat transfer of the heating assembly more uniform. In addition, by embedding the heating assembly in the liquid absorbing assembly, during the process of the vaporization liquid entering the liquid absorbing assembly from the side of the body portion away from the bottom wall and seeping out through the outer surface of the bottom wall, the heating assembly can preheat the vaporization liquid in the liquid absorbing assembly, so as to uniformly increase the temperature of the vaporization liquid, thereby improving the vaporization effect of the vaporization liquid. Further, by embedding the first embedding portions of the heating assembly in the annular side wall, the vaporization liquid at the liquid absorbing surface can be preheated. When the viscosity of the vaporization liquid is high, the vaporization liquid can be preheated, thereby improving its fluidity. As such, the vaporization liquid can quickly enter the liquid absorbing assembly through the liquid absorbing surface, and the rate of the vaporization liquid in the liquid absorbing assembly flowing to the vaporization surface can be enhanced, so as to timely replenish the vaporization liquid to the vaporization surface, thereby avoiding the problem of dry heating of the vaporization core.
